“Our new, Australian-style, points system is flexible to meet the needs of British business while ensuring that only those we want and no more can come here to work. This tough new ‘shortage occupation’ list supports that,” said Byrne.

“This strict list means 30% fewer jobs are available to migrants via the shortage occupation route. Those that do come will need to work hard, play by the rules and speak English.”

Positions like maths and science teachers will be open, as will civil and chemical engineers, quantity surveyors and project managers needed for property development and construction, but other jobs will face restrictions.
